Compact MMI-based AWGs in a scalable monolithic silicon photonics platform
2021
IEEE Photonics Journal
We demonstrate a compact (367× 67 µm 2 ) four-channel wavelength division multiplexer using an arrayed waveguide grating based on multimode interference couplers, and built on a monolithic silicon photonics platform. The design is particularly attractive due to the thin device layer. A seminumerical approach was used for device design and simulation. Optical measurements were found to be consistent with simulation results. The device channel spacing, 3-dB bandwidth and crosstalk were measured
